The classical application of gas-filled
surge arresters is to ensure the
primary protection of telecommuni-
cations installations against voltage
surges all the way from the main
distribution frames in exchanges to
the subscriber terminals. However,
the increasing use of fax machines
and modems for data transmission
has extended their application range
to protect the sensitive electronics
contained in this equipment. Surge
arresters are thus fitted at the input
of the power supply system together
with varistors and at the connection
points to telecommunications lines.
They have now become indispens-
able for protecting base stations in
mobile telephony systems linked to
large numbers of subscribers as well
as cable television (CATV) networks
with their extensive need for
repeaters and distribution systems.
The integral black-box concept offers
graduated protection by combining
arresters with varistors, PTC thermis-
tors, diodes and inductors to create
an ideal solution for many applica-
tions. The schematic diagram below
demonstrates typical applications
of surge arresters in a telecommuni-
cations system.
